There's one tiny spot in Iceland where you can touch 2 continents at once

The INSIDER Summary:

The Silfra fissure in Thingvellir National Park is one of the top dive sites in the world.

A crack between two tectonic plates, it's the only spot on Earth where you can swim between North America and Europe.

The glacial water is also crystal clear and clean enough to drink, but it's also a freezing 35 to 39 degrees Fahrenheit year-round.

If you're looking for your next adventure, you may want to head to Iceland.

One of the top dive sites in the world, the Silfra fissure in Thingvellir National Park is a crack between two tectonic plates. It's the only spot on Earth where you can swim directly between the North American and European continents.

Even better, the crack is filled with some of the clearest water in the world, which makes it the perfect place to snorkel. The only catch, however, is that the water is freezing cold — about 35 to 39 degrees Fahrenheit year-round, to be exact.

But if you're brave enough to dive in, you'll be submerged in beautiful glacial water from the nearby Langjökull glacier. And since this water is filtered through underground lava for 30 to 100 years before it reaches the surface of the lake, it's even clean enough to drink.

The best part? This breathtaking spot changes with the seasons, so you won't be disappointed no matter what time of the year you head there. In the summer, you can look forward to seeing colorful green algae underwater. In the winter, you can swim while snow falls down.
